I am new to the Aircraft Modification world. I have given a task to attach some Avionics equipment (only 2Kgs) to a small airplane (Twin Otter) fuselage, using appropriate mounting brackets.
The process I am following is
* Using Type certificate Found the Inertia requirements. ( Do I need to go through each FAR 23 amendment or use the Initial approved FAR 23 regulations? Di I need to consider existing running loads on Frames & stringers)
* Use the Inertia loading to find the mounting bracket bending , attachment fastener Shear .
(Since out of plane loads caused by bending due to the offset from Fuselage, can I use rivets? I read rivets are very bad in Tension, what could be the alternate fasteners?
* The fuselage skin is very thin (0.032") what could be the best option to stiffen the skin.
( Can I use doubler attaching to stinger )
